Learn how RFID technology operates using electromagnetic fields without a battery.

144 views

RFID technology works without a battery by using electromagnetic fields. The RFID reader emits a radio signal which powers the passive RFID tag. Once powered, the tag sends back its stored information to the reader. This mechanism allows passive RFID tags to operate smoothly without an internal power source, making them efficient and low-cost.

FAQs & Answers

  1. What is RFID technology? RFID stands for Radio-Frequency Identification, a technology that uses electromagnetic fields to automatically identify and track tags attached to objects.
  2. What are the benefits of passive RFID tags? Passive RFID tags are cost-effective, lightweight, and do not require a battery, making them suitable for various applications.
  3. How are RFID tags powered? RFID tags are powered by the electromagnetic fields generated by RFID readers, which activate the tags and allow them to transmit data.
